Ultrahigh pyroelectric figures of merit are achieved in a new phase‐transition material, di‐ n ‐butylaminium trifluoroacetate, of which the peak values are an order of magnitude larger than those of their inorganic counterparts. Such an attractive behavior of pyroelectric detectivity is strongly related to its distinct bistable dielectric behavior, which recalls excellent thermoelectric response in organic molecular phase‐transition systems.
